Hello, I am new to STM32 and keil µvison5.I have a STM32F407VGT6 I wrote a code and it's build successfully . But when I try to load ,it says "NO ST-LINK detected "Cannot enter debug mode" and "Error:flash Download Failed-Target DLL has been canceled"
I reinstalled everything from keil to the st-link utility. I reinstalled the driver en.stsw-link009 . But still the same problem. Also it's not detected by the st-link utility.So, any solutions ?
